WCDMA FDD Simulink Models

Simulation of a WCDMA FDD Downlink transmission.

Description

The WCDMA Physical Layer Demo consists of an end-to-end (transmitter-to-receiver) simulation of the Frequency Division Duplex (FDD) Downlink physical layer for several Dedicated Channels (DCH) as specified by the 3GPP standard (Release 99).

The current ZIP file includes three different models: channel coding, spreading and modulation and the complete physical layer. Some of the functionalities included in the models are: channel coding and decoding, interleaving, rate matching, mapping to physical channel, spreading, modulation and Rake receiver.

To run the model, unzip the file and type wcdmademos.

when we ran 3GPP WCDMA FDD (Rel 99) Downlink Multiplexing and Channel Coding Demo in Simulink 4.0
I get the Failed to find "Unipolar to Bipolar converter' in library 'communtil2' referenced by block 'wcdmamuxandcoding/Unipolar
Bipolar Converter'

I there anyway someone could make this block avaliable for us to download. It would be helpful if someone
post the instructions on how to 'install' this block so wcdma library we downloaded here can recognize it.

[Chanaka Gurusinghe]

When I ran wcdmaphylayer demo I get following errors:
1)scomerrate2 in block wcdmaphlayer/BLER Calculation/Error Rate
Calculation1 is expecting 7 parameters while 10 were provided in the block
dialog box.
2)scompnseq3 does not exist (even thought there is a file
called
scompnseq3.mexglx (as well as .dll and .mexsol exist in wcdmamex folder)
3)wcdmaratematching does not exist (same explaination)
4)scomcrcgen does not exist

I think errors 2-4 corresponds to simulink not recognizing s-function of
the extension (.mexsol for Sun OS and .mexglx for UNIX or .dll for
windows) in wcdmamex folder. How do I tell the simulink to reconginize
these files. (I already added location of wcdmamex, wcdmablks,
wcdmablksdemos, and wcdmamasks to the path using addpath command)

Hope someone post instruction on fixing these bugs.

It's a really good tool for people that studies the behavior of the channel of the WCDMA, for academic purpose, like me and my coleg.
The only problem is that it won't work in another MatLab version other than 6.1.

good ,but manny respects are not understanded by me

[Sander Stepanov]

Your designers are grate !
 Only one question how can I to work in code level Matlab or C, to use the elements of my code or to change Your code

[douglas lee]

 

[deepak jain]

it is good enough for experienced users, but try to make it more simple and commendable for first time users

[Asad Mahmood]

i am facing problems while simulating it with matlab 6.5.1 and it says that there are problems in bernoulli random binary generator and low pass filter.....does anyone knows what is going wrong??

[Peerapol yu]

I confirm the word of Asad Mahmood about the Bernoulli problem in simulation within MATLAB6p5

[N. S.]

I replaced file matlab\toolbox\commblks\commmasks\commblkbernoullisrc2.m
and It works. You have to copy commblkbernoullisrc2.m from MATLAB 6.0

[HA Viet]

I study at technology university of VietNam. Now, I have project about "simulink or demos of WCDMA systerm. I have just gotten your file. I am very interested with it. But now I face with a small problem, I the domos, It have a error "Error in block 'wcdmaphlayer/Bernoulli Random Binary Generator': Block initialization commands cannot be evaluated. MATLAB error message: Error using ==> commblkbernoullisrc2
Too many input arguments".
But I don't know how to solve it. May you please help me solve this problem.
Thank you very much.

But I don't know how to solve it. May you please help me solve this problem.
Thank you very much.

[Federico Gesualdo]

Hi, You could copy commblkbernoullisrc2.m from MATLAB 6.0 over the complete 6.5 version and it works. (matlab\toolbox\commblks\commmasks\commblkbernoullisrc2.m). The simulation is excellent.

[mahmoud mounir]

the simulation is so good but i have a problem running it.there is an error in binary generator that it has too many input arguments. i would be very glad if you help me in solving such a problem...thank you

[Tewfik BENABID]

-We'll be very glad if you study my application to
obtain the documentations of matlab
simulation for WCDMA system or other simulation for
this system.We have the simulation of
SNR with BER.
 
 -Being a students in 5 Years in Telecommunications
Engineering,and we have a project
(study and simulation of CDMA in UMTS networks).We
heard very intersting about the
formation that offers your organism, and thank you.
                    
                    our sincers
salutations.

[Satriyo widya]

The simulation good for visualitation, how about uplink and iteration?

[Paulo Ribeiro]

It would like to know you have some knowledge of a simulador like that that you developed, that simulate the uplink of the WCDMA. And it will have, would like to know itself and where the even is available.

I thank any information.

[barbaros preveze]

Dear sir

Even I have all the required blocksets and toolboxes mentioned above the programs gives the error below

"Error in block 'wcdmaphlayer/Bernoulli Random Binary Generator': Block initialization commands cannot be evaluated. MATLAB error message: Error using ==> commblkbernoullisrc2
Too many input argument"
I haven't changed any of the input parameters I've just downloaded and tried to run it but it doesn't :( could you please help me about solving this problem
Thank you very much

[Zuhair Alshaer]

I would like to ask if I have MPEG-4 file , and I would like to send it over WCDMA , if that is possible and how I can determine the DCCH. And which coding and which Modulation I should use? in this system.

[Zuhair Alshaer]

Dear Mr. Alex Rodriguez
Could u please advice me how to use the parameters of simulink in the case of WCDMA.

Hi, Alex. I'm student at Stttelkom. I have research about WCDMA Cell Searching. I see your simulation. I think it's very good. But I have some problem like Ali jaber. This is about random bernoulli and other. can you tell me what can i do. Thank u

[yousaf ismail]

Hello, if you people have understood how to build MEX files please tell me too. I have a big problem in creating 'mex' files.

Besides what are the propagation models used in WCDMA.... cost 270??

[Subin Chandy]

Dear Alex

Thank you for this model.

I tried to run the simulation and came across the problem:

Block initialization commands cannot be evaluated.
MATLAB error message: Error using ==>
commblkbernoullisrc2 Too many input arguments".

Could you please advice what is the best solution for this?. From the comments, I see that if we use "commblkbernoullisrc2.m" from Matlab 6.0 the problem may disappear. Could you please sent me this file?

Thanking You

Subin Chandy

hi!I have i problem whith the bernoulli block,can say what's the solution??

[khaled muhammed]

i need help i downloaded ur WCDMA from mathworks i added the wcdma library but i cant run any of ur demo blocks i get alot of errors each time i run them after i downloaded the zip file all i done was add the wcdma library and i believe i have 2 do something else in order 2 make ur block demos run and i have no idea wut 2 do so plz help me i'm so confused
thnx in advance

[md moinul islam]

This attempt is praiseworthy.This is useful
to me.i want more detail ideas from here.

[Nguyen Viet Anh]

It sound good!

[ayoub fettah]

I'm facing the same problem like khaled muhammed ,it activates many errors when i execute the demo.what can i do ?
